Its main function is to immerse the sinking roller as a whole in the molten zinc liquid, and cooperate with the stabilizing roller to stir the molten zinc liquid and apply it to the surface of the plate to be galvanized. In the prior art, the middle strength of the sinking roller is poor, and it is easy to deform when supporting stainless steel for a long time. At the same time, it is not stable when stirring the zinc liquid, so the accuracy and uniformity of galvanizing cannot be guaranteed. Therefore, there is a special need for a hollow sinking roller with a counterweight structure.

At the same time, the sinking roller may shift its position during the stirring process, resulting in galvanizing defects caused by the instability of the roller body, increasing the probability of defective products, and affecting the galvanizing efficiency of the plate.

[0020] The fixed counterweight mechanism 6 includes a fixed block 601, a mounting shaft 602, a limiting shaft 603, a fixed base 604, a first through hole 605, a second through hole 606 and a limiting block 607. One end of the connecting shaft 4 is fixedly connected to the fixed block 601, one end of the fixed block 601 is fixedly connected to the mounting shaft 602, one end of the fixed block 601 is fixedly connected to the limiting shaft 603, one end of the fixed block 601 is attached to the fixed base 604, a first through hole 605 is provided on the surface of one end of the fixed base 604, a second through hole 606 is provided on the surface of one end of the fixed base 604, and a limiting block 607 is fixedly connected to one side of the inner surface of the sinking roller 1. During use, the transmission shaft 5 will stably drive the connecting shaft 4 to rotate. At the same time, the sealing sheet 3 can provide a layer of protection for the sinking roller 1 to prevent the zinc liquid from infiltrating into the interior of the sinking roller 1. The mounting shaft 602 and the limiting shaft 603 cooperate with each other to allow the sinking roller 1 to stably stir the zinc liquid, thereby ensuring the efficiency of galvanizing the plate.

[0021] Furthermore, five groups of mounting shafts 602 are provided and are slidably connected to the first through holes 605. The fixed block 601 and the fixed base 604 are both slidably connected to the sinking roller 1 through the limit block 607. The provision of five groups of mounting shafts 602 can make the connection between the fixed block 601 and the fixed base 604 more stable, thereby ensuring the stability of the stirring of the zinc liquid and reducing the probability of the occurrence of defective products. The provision of the fixed block 601, the fixed base 604, the limit block 607 and the sinking roller 1 can allow the fixed block 601 and the fixed base 604 to be conveniently installed inside the sinking roller 1, thereby ensuring the overall stability of the sinking roller 1.

[0022] Furthermore, the sinking roller 1 is made of aluminum alloy, and the transmission shaft 5 is made of nickel foil. Through the setting of the sinking roller 1 made of aluminum alloy, the aluminum alloy material can transfer heat faster, which helps to maintain the uniformity of the zinc liquid temperature. Through the setting of the transmission shaft 5 made of nickel foil, the nickel foil material can remain stable at a higher temperature and adapt to the sealing requirements in a high temperature environment. At the same time, the nickel foil material has good resistance to various corrosive media.

[0023] Furthermore, the supporting mechanism 7 includes a sealing layer 701, a partition layer 702, a counterweight 703, a fixed plate 704 and a fixed shaft 705. The sealing layer 701 is slidably connected to one side of the inner surface of the sinking roller 1, the partition layer 702 is fixedly connected to one end of the sealing layer 701, the counterweight 703 is fixedly connected to one end of the partition layer 702, the counterweight 703 and one side of the inner wall surface are fixedly connected to the fixed plate 704, and the fixed shaft 705 is fixedly connected to one end of the fixed plate 704.

[0024] Furthermore, the sealing layer 701 is provided in two groups, and the counterweight blocks 703 are provided in four groups. By providing two groups of sealing layers 701, the overall sealing of the sinking roller 1 can be ensured, thereby reducing the occurrence of galvanized steel penetrating into the interior of the sinking roller 1, thereby extending the service life of the sinking roller 1. By providing four groups of counterweight blocks 703, the four groups of counterweight blocks 703 cooperate with each other to reduce the probability of defective products.

[0025] Furthermore, the limiting shaft 603 is fitted with the sealing layer 701. Through the setting of the limiting shaft 603 and the sealing layer 701, the limiting shaft 603 can be pressed against the sealing layer 701, thereby ensuring that the sinking roller 1 can cooperate well with the roller to stir the zinc liquid and apply it to the surface of the plate to be galvanized.

[0026] Working principle: During use, the transmission shaft 5 will stably drive the connecting shaft 4 to rotate. At the same time, the sealing sheet 3 can provide a layer of protection for the sinking roller 1 to prevent the zinc liquid from infiltrating into the interior of the sinking roller 1. The installation shaft 602 and the limit shaft 603 cooperate with each other to allow the sinking roller 1 to stably stir the zinc liquid, thereby ensuring the efficiency of galvanizing the plate. Through the setting of five sets of installation shafts 602, the connection between the fixed block 601 and the fixed base 604 can be more stable, thereby ensuring the stability of the stirring of the zinc liquid and reducing the probability of defective products. Through the setting of the fixed block 601, the fixed base 604, the limit block 607 and the sinking roller 1, the fixed block 601 and the fixed base 604 can be easily installed in the interior of the sinking roller 1, thereby ensuring the overall stability of the sinking roller 1. Through the setting of the aluminum alloy sinking roller 1, the aluminum alloy material can transfer heat faster. Through the setting of the nickel foil transmission shaft 5, the nickel foil material can remain stable at a higher temperature and adapt to the sealing needs under high temperature environment. At the same time, the nickel foil material has good resistance to a variety of corrosive media, which helps to maintain the uniformity of the zinc liquid temperature. During use, during the galvanizing process, the counterweight block 703, the fixed plate 704, and the fixed shaft 705 cooperate with each other to provide good stability for the sinking roller 1, thereby reducing the position deviation of the sinking roller during the stirring process, and improving the efficiency of the galvanizing of the plate. Through the setting of two sets of sealing layers 701, the overall sealing of the sinking roller 1 can be guaranteed, thereby reducing the occurrence of galvanizing penetrating into the interior of the sinking roller 1, thereby extending the service life of the sinking roller 1. Through the setting of four sets of counterweight blocks 703, the four sets of counterweight blocks 703 cooperate with each other to reduce the probability of defective products. Through the setting of the limiting shaft 603 and the sealing layer 701, the limiting shaft 603 can be against the sealing layer 701, thereby ensuring that the sinking roller 1 can cooperate well with the roller to stir the zinc liquid to adhere to the surface of the plate to be galvanized, greatly improving the efficiency of the galvanizing of the plate.
